SAFETY-SLEEVE FOR HING-ES AND THE LIKE.

To all whom it may concern:

Be it known that I, JAooB P. CROWN, a citizen of the United States, residing at Redwood City, in the county of San Mateo and State of California, have invented new and useful Improvements in Safety-Sleeves for Hinges and the like, of which the following is a specification.

This invention relates to a safety sleeve for hasps, leaf hinges, and the like, which is particularly adapted for use in connection with outside doors and gates.

The object of the invention is to provide a sleeve of this class which is so constructed and applied that the screws securing the hinge will not be exposed from the outside, thus making it practically impossible to remove the door or gate from its hinges while the gate or door is locked.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a perspective view of the safety sleeve. Fig. 2 is a perspective view of an ordinary leaf hinge to which the sleeve is adapted to be applied. Fig. 3 is a plan sec tion of the door and jamb showing the application of the invention.

For the purpose-of preventing the removal of outside doors and the like by thieves, which removal is sometimes accomplished by removing the screws from the hinges, a safety sleeve, generally indicated at A, has been provided. The sleeve A consists of a piece of metal bent substantially into the shape indicated in Fig. 1 and is adapted to be secured to the door by inserting screws through perforations 2 and 3 formed in the bottom portion of the sleeve. The upper face of the sleeve is provided with perforations 4, 5, 6 and 7. The perforations 5 and 6 are in line with the lower perforations 2 and 3 and are sufliciently large to permit the head of the screw to pass through the upper plate.

when applying the sleeve, it is accomplished by first placing it in position on the door and securing it by screws 8 and 9; the heads of which seat in the perforations 2 Specification of Letters Patent.

and 3. One of the leaves 10 of an ordinary type of leaf hinge, generally indicated at B, is then secured to the jamb of the door by screws 11 in the usual manner. The door is then placed in position and the opposite leaf 11 of the hinge inserted into the sleeve A. Leaf 11 is only provided with two perforations, indicated at 12 and 13, which are so positioned as to register with perforations 4 and 7 formed in the sleeve. Screws 14 and 15 are then inserted to further secure the leaf. The blank portion 16 of the leaf 11 will thus entirely cover the heads of the screws 8 and 9 and will thus make it impossible to remove the door from the hinges when the door is looked as it will be impos sible to remove the leaf 11 from the safety sleeve without opening the door.

The sleeve constructed as here shown may be cheaply manufactured and easily applied to any standard form of leaf hinge and when formed of thin metal will hardly alter the appearance of the hinge or occupy more space than usual. The material and finish of the sleeve are such as experience and judgment of the manufacturer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claim and that I do not wish to limit myself to the specific construction here shown.

Having thus described my invention, what i and means for securing the leaf in the sleeve.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JACOB P. CROWN.
